Accelerated Flight - Advance acoustic IOTA2 Manual

Caution: to keep good manoeuvrability make sure to fly your
IOTA 2 with enough airspeed while turning in thermals – not too
much outside brake .
Tip: if a brake line breaks you can steer the IOTA 2 using the C
risers .

Accelerated flight

The IOTA 2 has a weight–optimised line and wing design as well as ve-
ry balanced pitch behaviour in bumpy air . All this retains a very good
glide performance with only modestly increased sink rate in accele-
rated flight . 3 line levels, and the profile chosen for the IOTA 2 enab-
les the wing to be efficiently accelerated with little expenditure of pi-
lot energy .
The IOTA 2 wing remains extremely stable even in accelerated flight .
However, paragliders operate at a lower angle of attack while flying at
their higher speeds, and the degree of stability is generally reduced .
The higher aerodynamic forces involved at higher airspeeds mean that
a collapse can be more dynamic ( see also section «Collapses» ) .
When encountering severe turbulence while flying accelerated release
the speedbar fully before applying the necessary stabilising brake .
The IOTA 2's high degree of structural stability allows it to be flown in
normally turbulent air while accelerated . Active speedbar should be
employed for adjusting angle of attack under these conditions, instead
of brake . Pitch attitude disturbances can be minimised in this way, and
optimal glide performance can be maintained . See also section «Speed
system with SPI» .
when the angle of attack increases ( e .g . wing pitches back when en-
§
tering lift ), the speed bar is briefly pressed harder
when the angle of attack decreases ( e .g . wing pitches forward ), the
§
speed bar is released
Caution: even though the IOTA 2 is very stable in accelerated
flight you should only use as much speedbar as you feel hap-
py with .
Tip: make sure that brake is not applied at the same time as
speed bar, otherwise you will find yourself in the worst possible
gliding situation, without gaining any advantage .
Tip: Always choose a suitable speed for best glide taking into
account the actual headwind, sink rate ( descending air ) and ex-
pected next climb .
